Lucine

No summary available for this substance.

Lucine

Lucine, often spelled Leucine, is an essential branched-chain amino acid (BCAA) that is used for protein synthesis and muscle repair. It is known for its role in stimulating muscle protein synthesis, supporting muscle recovery, and providing fuel for intense workouts.

Category
Amino Acid
Molecular Formula
C6H13NO2
Mechanism of Action
Leucine stimulates muscle protein synthesis through activation of the mammalian target of rapamycin (mTOR) pathway. It also helps in the regulation of blood-sugar levels, growth and repair of muscle and bone tissue, growth hormone production, and wound healing.
Evidence Grade
B

“women who are in their reproductive years need around 35 grams of good protein highquality Lucine oriented protein within 45 minutes and we see that women who are per menopausal onwards are 40 to 60 grams because we become more anabolically resistant to food and exercise as we get older”

“Lucine is of particular importance for protein quality, the main anabolic component of protein is the branch chain amino acid Lucine which is a potent stimulator of muscle protein synthesis.”

“About 0.25 grams of protein per kilogram body weight in a single meal provides a saturating dose of Lucine and amino acids to stimulate muscle protein synthesis for up to 6 hours.”

“exercise causes Lucine to be taken up by muscle where it activates mtor in muscle to build and repair muscle rather than spending time in the bloodstream triggering mtor in the vascular system”

“Joe avick he had a paper in JBC where he looked at amino acid regulation of mtor this was this is before the lomes he was looking at the activity of using S6 kyes and he basically found a couple amino acids that mattered he found Lucine you know a very common essential Branch chain amino acid an important component of of whey protein for example that people take Arginine a very basic amino acid technically not essential lots of nitrogen in in that amino acid and those were the two big ones that he found.”

“the Holy Grail was how is Lucine detected that was the thing we wanted to know literally for decades and the reason was is that there's a lot of literature in mice in humans in big animals um you know used in farms that Lucine does cool stuff like boost satiety you know feeling of of having fed boost muscle mass and eventually we found it we found the receptor for Lucine it's a protein called sestrin.”

“the immediate idea was hey can we mimic the anabolic effects of Lucine without taking Lucine can we make something better than Lucine and and we've managed to make things slightly better but nothing dramatically better and the structure tells you why because it's it basically is made to fit Lucine and nothing else”

“the evidence would support two to three times that amount closer to 9 n gam of Lucine per day and just to calibrate us n gram of Lucine again is essential amino acid we can only get from food per day what does that equate to in terms of the total amount of let's say egg or steak protein that one would need to eat in order to ensure that just rough roughly yes.”

“is there a place for supplementing Lucine and other Branch chain amino acids specifically you know I always assumed that supplementing with Branch chain amino acids was kind of the unique domain of people you know post exercise trying to build more muscle but as you're telling me all this it seems that adding Lucine in powder form to a meal seems like it would be great for muscle health”
