Pap Pap Papain….
This post is just to share a recent experiment I did but before we get to that lets just take a minute and look at this logo.
To my knowledge this logo is misleading firstly the mixture they have is not 100% pure protein as the side of the box says it contains 15mg sodium in addition to 6g of proteins but I’m not here to argue that look at the back of the box.
It says , “Indulge gelatine contains important proteins for healthier skin, hair and nails.” This is misleading since we all know that gelatine is a hydrolysed form of the protein collagen and even though collagen does make up our skin and connective tissue we know that it is keratin that makes up our hair and nails and karetain and collagen are 2 completely different proteins.
- Collagen is made of 3 peptide chains which are left handed helix. These 3 helices are then coiled into a right handed coil (triple helix) forming the collagen structure. The peptide chains are predominantly made of glycine and proline and they both serve special roles within the molecule. Glycine works to stabilize since it is the smallest amino acid it fits on every third position of the chains which end up in the interior of the collogen structure or the center of the triple helix. Proline because of its cyclic structure aids in the formation of the coils in the triple helix structure of the collagen, since proline changes the direction of the chain due to is lack of maximum h bonds that can be formed.
- Keratin is a fibrous structural protein of hair, nails, horn, hoofs, wool, feathers, and of the epithelial cells in the outermost layers of the skin. The polypeptide chains of keratin are arranged in parallel sheets held together by hydrogen bonding.Of the amino acids in keratin, cystine may account for as much as 24 percent. The numerous disulfide bonds formed by cystine are responsible for the great stability of keratin: it is completely insoluble in hot or cold water and is not attacked by proteolytic enzymes (the enzymes that cleave protein molecules).
Gelatine is made from collagen thus according to the research it is rich in Proline and glycine both of which are non essential amino acids meaning our body makes them we do not get them from our diet….. thus the box is misleading, Further more it says that the gelatine is important for hair and nails and since we know that keratin is responsible for hair and nails and keratin is mainly made of cystine molecules the box is again wrong. (If it was made of cystine and keratin the following experiment would not have work as stated proteolytic enzymes such as papain doesn’t work in it)
Now the video which i made based on the enzyme papain and how it works (its my first video so please feel free to give any tips)…..
