tryptophan

organic compound, one of the 20 amino acids commonly found in animal proteins. Only the l -stereoisomer appears in mammalian protein. It is one of several essential amino acids needed in the diet; human beings cannot synthesize it from simpler metabolites. Young adults require about 7 mg of this amino acid per day per kg (3 mg per lb) of body weight. Nicotinic acid (niacin), a vitamin of the B complex, can be made from tryptophan in the body, but evidently the rate of transformation is insufficient for the demands of normal growth and maintenance, and hence nicotinic acid must be supplied in the diet. Deficiency of tryptophan in the diet enhances the progress of the vitamin-deficiency disease pellagra , which is treated by restoring nicotinic acid to the diet, usually supplemented with tryptophan. Bacteria in the intestine break tryptophan down to compounds such as skatole and indole, which to a great extent are responsible for the unpleasant odor of feces. Tryptophan contributes to the structure of proteins into which it has been incorporated by the tendency of its side chain to participate in hydrophobic interactions (see isoleucine ). The amino acid was isolated from casein (milk protein) in 1901, and its structure was established in 1907.

gta tryhard

Someone who tried playing call of duty and was trash at it, so decided to try and emulate cod gameplay in gta.

These people are normally 13 year old boys who have the joker as their profile pic, acts hard online despite them being a doormat in real life, watches too much anime and are also complete attention whores.

A characteristic of gta tryhards is acting like kd ratio matters in gta and arguing that everyone should care, which is stupid because no one under the sun considers gta a competitive game. They will normally have a gta character that looks like kaneki ken if he was retarded.

This behavior ruins the game for everyone else trying to have fun, trying to grind, or just about anyone who isn’t an inbred douchebag.

Gta tryhard: ohhhh 1-0 you got destroyed!
Normal person: I don’t care....
Gta tryhard: -insert mum joke-
Normal person: *block*

busier than a cat trying to bury a turd on a frozen pond

A phrase your grandparent might use to describe being busy with a futile, impossible, or endless task.

Cats like to cover their feces, but if they've done their business on a frozen pond, no matter how long they try to dig up something to cover it with, their paws will always slide on the ice. The joke is the mental image of a cat making the digging motion on ice for a long time.

I don't know why I keep weeding that garden. I've been busier than a cat trying to bury a turd on a frozen pond, but I tell you what, there's gonna be just as many dandelions tomorrow.
