Remember that amino acids are held together by a peptide bond! This is an image from our protein synthesis video! We go over the steps of transcription and translation and the roles that ribosomes, DNA, and RNA play. We also compare and contrast RNA and DNA and explain the three different types of RNA. Come learn and laugh with the zany Amoeba Sisters! https://www.youtube.com/watch?v=h5mJbP23Buo
There’s only one place we welcome stains: on our lips. This smooth, hydrating balm nourishes and protects lips while giving us a boost of long-lasting natural colour for a your-lips-but-better stained look. Hydrating peptides bond with water to smooth and soften dry skin, while green tea extract protects lips with a boost of antioxidants.
The primary structure refers to amino acid linear sequence of the polypeptide chain. The primary structure is held together by covalent bonds such as peptide bonds. The primary structure of a protein is determined by the gene corresponding to the protein. A specific sequence of nucleotides in DNA is transcribed into mRNA, which is read by the ribosome in a process called translation.
Enzymes. Proteases - break down proteins. Amylases - break down starches. Lipases - break down fats. Proteases decompose big, water-insoluble protein molecules into small soluble units by breaking the amide (peptide) bonds between amino acids. Amylases decompose big, water-insoluble starch molecules into small soluble units by breaking the ester bonds between sugars in starch. Lipases break the ester bonds in fatty acids. In each case the reaction is a hydrolysis (reaction with water).
