They are both nucleic acids. Regarding structure, DNA and RNA are similar because they are both built of nucleotides, structures consisting of one nucleobase, a sugar (ribose or deoxyribose respectively) and a phosphate group.
Recent intake recommendations to meet the lysine requirement range from 64 to 30 mg/(kg Â· d) for 0.5-y infants and adults (>18 y), respectively. Lysine intake in the Western human diet is in the range 40â180 mg/(kg Â· d). An upper limit of 300â400 mg/(kg Â· d) can be considered in humans. l-Lysine is a basic amino acid characterized by the presence of an amino group at the end of a 4-carbon aliphatic side chain [-(CH 2) 4-NH 3 +].
Lysine (also known as L-lysine) is also an amino acid, and can be used to trick the virus. The herpesvirus tries to use the lysine to reproduce, but it can't replicate as quickly or as efficiently. The Merck Veterinary Manual recommends a dosage of 250 to 500 mg of lysine a day. You can double the dose while your feline friend is having an outbreak. Always consult your vet before giving your kitty lysine supplements or changing her dosage.
